Diet
A blue-tongued skink will eat both plants and animals. Insects should be their staple, or main food source. 60% of their diet needs to be insect, the rest plant. Plants that can be used as food include a mixture of greens. The darker the vegetable, the healthier it will be.
Crickets, mealworms, super worms, and even pinkie mice can be fed to your blue-tongued skink. Pinkie mice should not be fed constantly, or else the skink has a higher chance of getting fatty liver disease. Mealworms are better for babies because if you feed them to adults, they are not as filling, and would need to be fed in bulk.
